What does “straight” pleats do for us?
Tells us the media bundle wasn't buckled by excessive compressive stress, and didn't warp due to moisture.
On the buckling by excessive compressive force: I’ve seen this brought up a couple of times - Doesn’t the center tube support the compression? It doesn’t seem that the media should be under any compressive stress. Is there something I am missing?
I like the fact that some oil filter manufacturers put the plastic on the base plate. I'm sure this is done to keep the internal parts free from contaminants and the base plate rust free as well. I'm sure there is an extra charge for this plastic to be produced. Is it that much cost as to why the BIG filter makers can't do the same?
Thanks for the C&P.
I agree that it is a nice touch. The o-ring was pre oiled as well. One of these, I’m pretty sure it was this one, the plastic was cracked where it wrapped over the seam and wasn’t held very tight.
You’re welcome for the C&P.
Thank you and you’re welcome.
I’m still a bit puzzled by the hoopla on these, it appears to be nothing very special. If it was one of the majors like Fram, Purolator or Wix they’d be called on the carpet for not posting efficiency numbers (at least I can’t find any) , saying a black ADBV is silicone and using a picture of endcapless media in the literature.
This one BTW was a little over 6 bucks and fits 7317 applications.
